A few months back I had an aftermarket bluetooth radio installed in my car. And just prior to that my key fob stopped working, but the power lock/unlock controls on the inside of my car were working. After I had the radio installed, the power lock/unlock stopped working and I also cannot open up the hatch at the rear of it, because the only way to unlock and lock it is with the power lock/unlock. I'm not sure if the issue is connected to the new radio, but it could be for all that I know.
Do you

Hello,

Okay, so first lets check the fuse and make sure that it isn't blown. It's fuse #18 in the fuse junction panel on the left side of the vehicle under the dash. In the diagrams down below I have included a wiring diagram of the power door locks in your vehicle as well a diagrams of the location, fuse junction panel with callout for your vehicle. Please look over these guides and get back to us with what you find out about the fuse. I have also included a link below for you if you need to know how to check a fuse as well.

So I checked fuse #18 and it was blown, so I went to AutoZone to buy another, and I got a pack of 4 bussman 25 amp fuses (they were clearish/white). I put one in and as soon as I tried to lock my car, it blew. Then, I tried it one more time just to make sure that it wasn't a fluke, and it blew again.

Hello,

Okay, the fuse keeps blowing because you have a short to ground in the power door lock circuit. In the diagrams down below I have included wiring diagrams for your vehicle's door lock circuits and a guide on how to find short to grounds in an automotive electrical circuit. Here is a link on how to use a digital multi-meter (DMM), as you will need to use one to find the short to ground.

Please go through these guides and get back to us with what you are able to find out.
